Questions about cavity wall insulation

How do I know if my house has cavity walls?

Many homes built from the 1920s onwards have cavity walls: two layers of brick with a gap between them. A quick clue is the brick pattern. If every brick shows its long side, it is often a cavity wall. Bricks showing their short ends in the pattern usually mean a solid wall. We confirm it on our visit.

Is cavity wall insulation messy?

No. The insulation goes in from the outside through small holes drilled in the mortar, which are filled and matched afterwards. Most homes are done in a day and nothing needs moving indoors.

Can insulation cause damp?

Insulation that suits the property and is fitted properly should not cause damp. That is why we look at the walls, roof and ventilation before recommending anything, and tell you plainly if a property isn't suitable.
